Crow Kills

 Researchers for the Massachusetts Turnpike Authority (MTA) found over 200 dead crows near greater Boston recently, and there was concern that they may have died from Avian Flu. A Bird Pathologist examined the remains of all the crows and, to everyone's relief, confirmed the problem was  definitely NOT Avian Flu. The cause of death appeared to be vehicular 
impacts.

 

However, during the detailed analysis, it was noted that varying colors 
of paint appeared on the birds' beaks and claws. By analyzing these 
paint residues, it was determined that 98% of the crows had been killed 
by impact with trucks, while only 2% were killed by an impact with a car.

 

MTA then hired an Ornithological Behaviorist to determine if there was a 
cause for the disproportionate percentages of truck kills versus car 
kills.

 

The Ornithological Behaviorist very quickly concluded the cause: When 
crows eat road kill, they always have a look-out crow in a nearby tree to 
warn of impending danger. They discovered that while all the lookout 
crows could shout "Cah!", not a single one could shout "Truck!"

Ah! Science!!!!!
